Buncrana Castle and O’Doherty’s Keep, Buncrana

Located near the mouth of the Crana River by Castle Bridge, approximately 1.5 km north of Buncrana Tourist Office, this historic area offers a fascinating glimpse into Inishowen’s Gaelic and plantation-era past.

The O’Dohertys were the Gaelic lords of late medieval Inishowen, rising to prominence after the departure of the Normans—who had defeated the original Cenél nEógain rulers, the MacLaughlins, at the Battle of Cameirg in 1241 AD.

The small tower house known as O’Doherty’s Keep, situated on the Crana River, was of secondary importance compared to the O’Dohertys’ main strongholds at Elagh and Burt. Its original two-storey structure, of Anglo-Norman influence, was probably built between 1410 and 1430.

Around 1602, towards the end of the Nine Years’ War, a third storey and other modifications were added for the young Sir Cahir Rua O’Doherty, the last Lord of Inishowen.

Following Cahir’s failed rebellion and death in 1608, the English Crown’s Lord Deputy, Arthur Chichester, secured most of Inishowen for himself. During the Plantation of Ulster (c.1610), he leased O’Doherty’s Keep and its lands to Captain Henry Vaughan, an English army veteran.

Vaughan’s grandson, Colonel George Vaughan, built the nearby manor house, Buncrana Castle, between 1716 and 1718, marking a new era in the area’s history.
